4 Claims. (01. ss-9) The invention relates to weh; hooks for turnlng weit on a. full fashioned knitting machine.

One object of the invention is to provide a welt hook, the point of which will be shielded aga.ins t contact with the stitch when this is pushed down onto the needle from the we1t implement onto the knitting needle.

In the accornpanying drawing Figure 1 is a view of the improved welt implement looking at it from the front thereof.

i. e., et the face on which the hook is 'located.

Fig. 2 is a side view cf the improved implement. Fig. 2a is a cross section of the implement on the line 2a2a-of Fig. 2.

Flg;2b is a cross section on the line 2b2b f Fig. 2.

Fig. 2c is an enlarged view of the hook of Fig; 1 and the adjacent pait ofthe stem of the welt implement.

Fig. 3 is a diagrammatic view of the improved weh: implement in position relative to the knitting needle with the upper layer or section of the welt; fabric ready to be pushed down onto the knitting needle.

Fig. 4 is a diagrammatic view similar to Fig. 3 with the upper 1ayer of the wel t fabric pushed down onto the stem of the needle below the beard thereof adjacent the under layer of the weh: ready to proceed with the knitting of the leg fabric.

Fig. 5 is a modification showing that the stem, near the hook, instead of tapering to the noseof the Welt implement may be otherwise reduced in width below the plane where said stem shields the point of the hook.

The improved welt hooks are mounted in a row in a transfer bar (not shown) as in ordinary practice to receive the loops of the first course of knitting; and 130 hold the same while the desired length of fabric is knit for turning the welt. This implement has a stem or main body l provided with a butt 2 by which th'e implement is mounted in the ordinary transfer bar.

i. e.the same face on which the' hook 4 is lo- It is provided with an e&e 3 on its front face,

The stem at 6 is of 1ess width than the width of the main body of the implement which contains the eye 3, but on the other band, this portion 6 of the stem just above the hook is of cousiderably greater width, comparativel& speaking,

than the width of the hook itself, and this is particularly so of that portion which lies adiecent the hook where it is tapered in width to form the point.

In other words, the point of the hook lying in the longitudinal Center plane of the stem 6 of the implement is spaced apart a substantial distance, comparatively speaking, from the adjacent side fades of the stem portion 6, so that the point of the hook lying close to the face of the wider stem portion 6 is shielded by this comparatively wide stem portion from contact with the loop on the implement. Therefore, as the 100p a, Fig. 3, is pushed downwardly a1ong the hook end of the implement, it will not be caught by the hook, but, on the contrary, it will move freely past the hook from the position shown catedi The point; cf this hook, instead of being widely separated from the-stem of the-implement, is separated from the face cf the stem by only aslight space, as indicated at 5 in Fig. 2. other words, 'the point of the hook is made to lie es close as possible to the face of the umlerlyihg' stem, consistent with its capacity to receive the yarn therein, which, in fine gauge machines, is very close.

vtapers to the nose of the implement at I.

in Fig. 3 to the position shown in Fig. 4, lodging on the stem of the spring beard needle below the beard thereof in which position it is entirely free from the weh: hook, and is completely positioned on the needle stem in such relation to the beard that when the Operation .of knitting isproceeded with, involving the pressing oi said beard, it will be cast 01T togetherwith the p a of the lower 1ayer of the weh; and become a part of the fabri'c.

The wide part cf the stem 6 of the implement extends to a point.near a transverse plane at;

about the middle of the length of the hook, as

viewed in Fig. 1. From this poir'1t indicated a.t T, the width of the stem underlying the hook At this end, the implement is small in width.

It will be noted from Figs. 3 and 4 that in the loop transfer operation, the hook of the weit turning implement lies against the back of the needle, where it is additionally shielded by the s tem of the. needle from catching the yarn. A1- though t-he welt turning implement'of the invention is illustrated in these figures in association with a knitting needle having an eye in the side thereof qpp0site from the beard side for receiving the hook of the implement, the in- "the berid" of the hook.

implement where the stem may be termed the nose" meres into the hook of said implement, or

Fig. 2 shows that the in'ner face of the hook which lies close to the stem 01 the implement 1s substantially parallel with the opposing face oi sa.id stem. The hook is sufllciently rigid to permanently maintain this relationship, since this iriif lement ls not of the yielding or spring bea.rd

he we1t bar maybe connected up in the imitting machine under tension in the usuai manner, after being operated by band.

The invention is not limited to a band operated weit bar, becausethe improved transfer hook may be employed in an automatic machine without departing trom the scope of the invention.

The invention is not limited to the tapered form of the sten'1 of the needle between the zone T and the point where it merges into the base of the hook. For instance the end of the stem adjacent the hook can be 01 the form shown in the erilarged view Fig. zone which corresponds substantially to the zone T of Fig. 1'the end of the stem is abruptly reduced in width, instead 015 being reduced by a. gradua taper. This abrupt reduction in width howevm, is so located that the point 'of the hook is still shielded b y the the Stern begins at a level weil below the level cf the point of the hook so that said point will beshielded by the wide stem adja.cent seid point.

I claim:

1. A Welt turning implement comprising a stem portion and a. rigid returned portion lying in a fixed position appmximately parallel to but spaced from the stem portion to form a permanently open hook, said stem portion having an eye therein an the same side tiiereof with the returned portion and loca.ted along the stem spaced from the returned portion to receive the end of a. knitting needle, s aid returned portion having a. pointed end, und said stern portion increasing in width a.way from the end of the implement where the returned portion merges into 5, in which form from the wide portion of the stem. In other words, fihe abrupt reduction in width of the stem portion so that the stem portion is wider at its part underlying seid pointed end than any the returned portion being wider than any part;

of the returned portion whereby the point of the implement will be shielded against catching in the yam of a loop, und also beim; wider than the end where the returned portion merges in the stem.

3. A weit turning implement comprising a stem portion and a rigid returned portion lying in a flxed position spaced from the stem portion to form a, permanently open hook, the end of seid returned portion being pointed, and the part 615 said stem portion which is adjacent to the pointed part of the returned portion beim; wider than any part of therctrned portion whereby the point of the implementwill be shielded against catching in the yarn of a. Icon, the part of the stem portion adjacent to the unpointed part of the returned portion being no wider than this unpointed part of the returned portion.

4. A weil: turning implement comprising a stem portiou and a rigid retumed portion lying in a fixed position spaced from the steril portion to form a permanently open hook, the end of said retumed portion being pointed, and the part ol said stem portion which is adjacent to the pointed part of the returned portion being wider than any part o'lf the returned portion whereby the point cf the implement will be shielded against catching in the yarn 01 a 1oop, the part of the stem portion adjacent to the unpointed part of the returned portion tapering gradually from the widened part 015 the stem portion to the end of the implement where the returned portion merges into the stem portion.
